Description

TECHNICAL FIELD

[0001] The invention relates to a preparation module for arrangement in a receiving area of a kitchen device base, in particular of a kitchen device base of a kitchen device. The preparation module has at least one preparation vessel and at least one lid. The preparation vessel has at least one preparation chamber for receiving food and at least one lid locking unit. The lid locking unit has at least one locking mechanism. The lid can be removed from the preparation vessel in at least one lid release position of the lid locking unit and closes the preparation chamber in at least one lid locking position of the lid locking unit. In the lid locking position, the lid is locked with the preparation vessel. The locking mechanism is designed to prevent a movement of the lid locking unit into the lid release position in the locked position at least when a force from the preparation chamber acts onto the lid or when the lid is pulled by a user, in particular in a direction parallel to a longitudinal axis L of the preparation vessel. BACKGROUND

[0002] Kitchen devices of various design are known from the prior art, which have a kitchen device base and a preparation module, for example comprising a preparation vessel and at least one lid. Such kitchen devices are used for the automatic, semi-automatic or manual preparation, for example comminution, grinding, pressing, stirring, cooking, steaming and / or warming of food. The kitchen devices usually have a kitchen device base, which provides at least one receiving area for at least one preparation module, for example with a preparation vessel. The receiving area usually has at least one electrical interface in order to supply at least one working voltage for a preparation module arranged in the receiving area, for example for a heating device of the preparation module, or in order to contact a sensor, for example.

[0003] Alternatively or additionally, at least one mechanical interface, for example a tool interface, is provided in the receiving area, for example for transmitting a torque from a working unit, for example a motor, of the kitchen device base to a tool arranged on the preparation module.

[0004] In order to lock the lid with the preparation vessel, for example when preparing food in the preparation vessel, the preparation vessel has at least one lid locking unit, by means of which the lid can be fixed and can be released. The locking mechanism interacts with the lid locking unit and prevents a movement of the lid locking unit into the lid release position at least when a force from the preparation chamber acts onto the lid.

[0005] However, the locking mechanisms known from the prior art have the disadvantage that, in order to prevent the escape of a rotating liquid vortex, a dwell time is carried out before the lid is unlocked, in order that the liquid vortex can subside. However, this is carried out even if no liquid vortex is actually formed. Thereby, a waiting time is generated for the user, which reduces the user comfort. SUMMARY

[0006] The application is therefore based on the task of providing a preparation module having a preparation container and a kitchen device in which advantageous locking and unlocking of the lid can be achieved, but at the same time a high user comfort is ensured by reducing the waiting time when the lid is unlocked.

[0007] The task is solved in a preparation module of this type having the features of the characterizing part of claim 1, i.e. by the lid locking unit being moved at least partially in the direction of the lid release position when the locking mechanism is in the locked position, and the locking mechanism being brought into the locked position at least by translational movement of the lid.

[0008] The preparation container of the preparation module is configured and designed for arrangement in a receiving area of a kitchen device base of a kitchen device. When used together with the kitchen device base, the preparation module serves for automated, semi-automated or manual preparation, in particular of food, such as for example comminution, grinding, pressing, stirring, cooking, steaming and / or warming. The preparation container has in particular at least one electrical heating mechanism for heating a preparation chamber. Furthermore, the preparation container has at least one electrical interface, for example for contacting the heating mechanism and / or for contacting a sensor. The electrical interface is in particular configured for cooperation with an electrical mating interface of the kitchen device base.

[0009] Furthermore, the preparation container preferably has at least one mechanical interface, for example for transmitting torque for a tool, which is configured for cooperation with a mechanical mating interface, in particular a tool interface, of the kitchen device base. The preparation container preferably has at least one rotatable tool, which is fixedly connected to the preparation container or is releasably held in the preparation container, in particular on a tool holder. In particular, the tool is coupled to the mechanical interface.

[0010] The preparation chamber of the preparation container can be closed with a lid, wherein the lid can be locked with the aid of a lid locking unit. Advantageously, at least one seal is arranged between the lid and the preparation container. Preferably, the seal is configured for centering the lid when placed. For example, the seal is held on the lid by a welded retaining ring. Advantageously, the lid locking unit can be moved, in particular rotated, between a lid release position, in which the lid can be removed, and a lid locking position, in which the lid closes the preparation chamber and is locked with the preparation container.

[0011] According to one design, the preparation module has at least one preparation container and at least one lid. It is preferably provided that the preparation module has at least one lid, in particular for at least partially or completely closing the preparation chamber. It is, however, also provided that a lid which is not used for or not only used for closing the preparation container can be locked using a lid locking element. The preparation module preferably has at least one functional module. The functional module can be placed onto the lid and / or the preparation container and / or can be partially or completely inserted into the preparation container, in particular into the preparation chamber, for example. The functional module is configured as a kit accessory or an insert accessory, for example. It is particularly preferred that the lid is configured as a functional module. This is synonymous with the functional module having a lid interface.

[0012] It is further advantageously provided that the functional module has at least one connection interface for interaction with a tool and / or a tool holder of the preparation container, for example for rotation of the tool. This is particularly meaningful in a functional module which has a tool function, an accessory tool, for example a juicing module, a cutting module or a shelling module.

[0013] It is particularly preferred that the functional module has at least one lid interface for interaction with a lid locking unit, in particular a lid locking element, of the preparation container and for locking and unlocking the functional module, for example the lid, with the accessory container. In use, the functional module is reliably held on or in the preparation container by the interaction. In this sense, the functional module constitutes a dedicated lid, in particular. The lid interface preferably has some or all of the features of the lid which are required for interaction with the lid locking unit, in particular the lid locking element. This is in particular at least one or more lugs and / or centering elements and / or support units, for example.

[0014] The functional module is a cleaning module, a stirring module, a juicing module, a steaming module, a warming module, a shelling module, a cutting module or a rubbing module, for example. Any of the aforementioned functional modules is configured as an insert or a kit, for example a cleaning insert or a cleaning kit. A functional module which does not have a lid interface and can be completely inserted into the preparation chamber can be used with a conventional lid, in particular.

[0015] In particular, the lid or the functional module does not rotate when being locked and unlocked. When being locked or unlocked, a translational movement parallel to the axis of rotation is preferably only carried out. Rotation of the lid or the functional module is preferably prevented by interaction, in particular form-fit interaction, of a support element on the preparation container and a support counter-element on the lid.

[0016] The preparation container preferably has at least one handle for transport and for easier handling. The handle is in particular oriented essentially vertically and arranged on the outside of the housing of the preparation module.

[0017] The interplay of the locking mechanism and the lid locking unit thus makes it possible to prevent a continued movement of the lid locking unit into the release position when a force acts on the lid in a direction parallel to the longitudinal axis of the preparation vessel or the rotational axis of the tool. The force in this direction is caused, for example, by a rotating liquid whirl or by pressure. Likewise, such a force is caused when the user manually pulls on the lid. In the following, only the case of a force from the preparation chamber is referred to by way of example; however, these explanations apply equally to a translational movement of the lid caused by the user.

[0018] According to the application, the interplay between the locking mechanism and the lid locking unit only occurs when the lid locking unit is moved at least partially in the direction of the release position. Thus, the locking position of the locking mechanism can only be reached when the lid locking unit has already been moved at least partially in the direction of the release position. This has the advantage that the user can recognize that there is no false blocking of the lid locking unit, but rather that the blocking occurs as a result of a force acting on the lid.

[0019] The locking mechanism is designed in such a way that a continued movement of the lid locking unit into the release position is prevented when the lid is moved in translation relative to the preparation vessel, i.e. is pushed or lifted away vertically upwards, for example. In particular, the locking mechanism prevents a possible unintentional escape of liquid or food from the preparation chamber. By means of a force from the preparation chamber or a force of the user, the entire lid is advantageously moved slightly away from the preparation vessel, in particular in a direction parallel to the longitudinal axis of the preparation vessel or the rotational axis of the tool, as a result of which the locking mechanism is brought into the locking position. In particular, the lid can be lifted slightly upwards from the preparation vessel without removing the lid from the preparation vessel. In particular, it is not only provided that at least one opening to the preparation chamber is configured by means of the translational movement of the lid, through which opening steam can escape or the pressure can be reduced in a targeted manner, but also that the lid also closes this preparation chamber after the translational movement. In particular, it is provided that the lid is not circular, but is designed in an elliptical shape.

[0020] It is preferably provided that the lid is only moved in translation in the axial direction, in particular parallel to the longitudinal axis of the preparation vessel or the rotational axis of the tool, when the lid locking unit is moved between the locking position, the release position and the locking position. In particular, no rotation of the lid itself occurs when locking and unlocking. Preferably, the lid locking unit is rotatable between the lid locking position and the lid release position.

[0021] Compared to the prior art, the application has the advantage that the opening of the lid can be caused directly after the preparation of the food. This is recognized only as a result of a translational movement of the lid caused by a force from the preparation chamber, which actually acts on the lid, as a result of which a continued release of the lid is blocked. If no force is exerted on the lid, an opening without interruption occurs, as a result of which a delay of the opening process only occurs when required, as a result of which the user comfort is improved by the omission of a waiting time and at the same time a high level of safety is ensured.

[0022] Especially preferably, according to a first design variant of the preparation container, the locking mechanism has at least one first locking surface and at least one locking element, and by the locking element lying against the first locking surface, the translational movement of the lid is limited. In particular, when the locking mechanism lies against the first locking surface, the locking mechanism is then in the locked position. By the locking element lying against the first locking surface, the translational movement of the lid away from the preparation container is limited. Preferably, the first locking surface is oriented substantially orthogonally to the movement direction of the lid. Especially provided, the locking mechanism has a plurality of first locking surfaces, preferably at least three or exactly three or at least four or exactly four first locking surfaces. For example, the locking element is arranged on the lid and the locking surfaces are arranged on the preparation container.

[0023] For example, provided, the first locking surface is a surface in a recess. In particular, the lid locking unit has at least one recess, the first locking surface being part of the recess. Preferably, the lid is moved slightly away from the preparation container in order to bring the locking element to lie against the first locking surface. For example, provided, this movement of the lid is recognized by a sensor, for example a position sensor, which then immediately stops the continued movement of the lid locking unit, for example by stopping the motor of the drive unit.

[0024] In particular in order to be able to realize a mechanical blocking of the locking mechanism, according to a further design variant of the preparation module, the locking mechanism has at least one second locking surface, and in the locked position the locking element is mechanically prevented from a continued movement in at least one direction, in particular in the direction of the release position, due to at least partial lying against the second locking surface. For example, the second locking surface is a surface of a recess. Preferably, the second locking surface is oriented substantially parallel or obliquely to the movement direction of the locking element when the lid is moved, or parallel or obliquely to the longitudinal axis of the preparation container. Thus, if for example the lid locking unit is rotated in the direction of the lid release position, a continued rotation of the lid locking unit is mechanically prevented by the locking element lying against the second locking surface. Especially provided, the locking mechanism has a plurality of second locking surfaces, preferably at least or exactly three, or at least or exactly four second locking surfaces.

[0025] Preferably provided, the mechanical blocking of the locking element by the second locking surface is recognized, for example by detecting the current strength on the motor of the drive unit, so that the drive of the lid locking unit can be switched off, in particular by the control unit of the kitchen device base. For example, the first locking surface and the second locking surface are oriented at an angle of between 80° and 155°, preferably between 120° and 140°, in particular 90° or 135°, relative to one another. For example, the second locking surface is a side surface of a recess. Preferably, the locking element in the locked position not only lies at least partially against the first locking surface, but also at least partially against the second locking surface.

[0026] The invention can be realized in a simple manner by the following measures, according to one design variant the lid locking unit has at least one lid locking element which is held in a manner rotatable about an axis of rotation, and at least a first locking surface is configured on the lid locking element. Preferably, the lid locking element is configured annularly. For example, the lid locking element is held on the preparation container in a manner rotatable relative to the lid and relative to the preparation chamber. For example, a rotation of the lid locking element in a first rotational direction causes a locking of the lid to the preparation container. For example, a rotation of the lid locking element in a second rotational direction opposite the first rotational direction causes a release of the lid, provided that the movement in the second rotational direction is not blocked by a locking mechanism, in particular a locking element which cooperates with the first locking surface. Preferably, the locking element is arranged on an inner surface of the lid, and the locking surface is arranged on a radially outwardly directed surface of the lid locking unit or of the lid locking element.

[0027] Preferably, the lid locking element is arranged in such a way that it is almost completely covered by the lid. Preferably, the size of the visible portion of the lid locking element increases when the locking mechanism is in the locking position, i.e. when the lid is at least partially lifted from the preparation chamber.

[0028] According to a further design variant of the preparation module, the lid locking unit for locking the lid has at least one locking slide and at least one lug. The locking slide forms a profile in which the lug is guided when the lid locking unit is moved in order to lock or unlock the lid when the profile is moved, in particular rotated, relative to the lug. For example, the locking slide has at least one start-up ramp which causes a pulling of the lid to the preparation container in a manner cooperating with the lug, in that the lug slides on the start-up ramp. Preferably, at least the first locking surface and / or the second locking surface of the locking mechanism is configured on the locking slide or in the course of the locking slide. Preferably, the first locking surface is configured in direct abutment with the start-up ramp.

[0029] The start-up ramp is preferably configured in such a way that it causes at least an axial movement of the lug in a direction parallel to the longitudinal axis of the preparation container when the lid locking unit is moved, in particular when the lid locking element is rotated. Thereby, the lid is approached along the longitudinal axis to the preparation container over a stroke, which the lug is also moved by the start-up ramp.

[0030] Advantageously, the lid locking unit has at least or exactly two, at least or exactly three, or at least or exactly four locking slides and has at least or exactly two, at least or exactly three, or at least or exactly four lugs, in particular wherein one lug cooperates with one locking slide, respectively. For example, the locking slide has at least one locking surface. In the lid locking position of the lid, the lug rests on the locking surface and is blocked by the locking surface from a movement in a direction parallel to the longitudinal axis of the preparation container, thereby locking the lid to the preparation container.

[0031] Alternatively or additionally, the first locking surface is arranged axially, in particular in a direction parallel to the longitudinal axis of the preparation container, offset with respect to the locking surface. For example, a step is configured between the locking surface and the locking surface, which defines the magnitude of the axial translational movement of the lid.

[0032] In order for the lugs to be able to interact with the lid locking unit or the lid locking element, the inner pot has a corresponding number of recesses in the upper edge, corresponding to the number of lugs. In particular, at least or exactly four recesses are provided. The recesses are preferably arranged in pairs, wherein an angle of approximately 60° is configured between a pair of recesses (measured from the longitudinal axis L). An angle of approximately 120° is respectively configured between two pairs of recesses.

[0033] It has proven particularly advantageous according to a further design of the preparation container that the lugs are also locking elements of the locking mechanism, which are pressed into a locking position, in particular into a recess, in the movement in the direction of the lid release position if a force acts on the lid during the movement, in particular in a direction parallel to the longitudinal axis of the preparation container. Preferably, a first locking surface of the locking mechanism is arranged between the starting ramp and the locking surface of the locking runner. Thereby it is ensured that the locking mechanism moves, in particular rotates, past the first and / or second locking surface when the lugs are moved in the direction of the lid release position from the lid locking position and only comes to rest on the first and / or second locking surface when a force acts on the lid or can continue to move in the direction of the lid release position when the lid is not stressed.

[0034] Preferably, the lugs are arranged on the lid and the locking runner is arranged on a lid locking element which can be rotated about a rotation axis. Thus, the lugs are guided by the locking runner in order to lock the lid with the preparation container, but the lugs are also used to block the complete unlocking of the lid when the force acts on the lid. Preferably, the lugs rest on the first and second locking surfaces in the recess in the locking position. The recess is configured, for example, between the locking surface and the starting ramp on the locking runner. The recess is configured, for example, as a setback directly between the end of the starting ramp and the locking surface.

[0035] Only when the force actually acts on the lid in a direction parallel to the longitudinal axis of the preparation container are the lugs pressed into the recess. If the force does not act, the lugs pass over the recess and thus over the first and / or second locking surface and reach the lid release position without a waiting time for the user.

[0036] In another embodiment of the preparation module, the first locking surface is arranged in a recess. Preferably, the recess has at least one guide ramp, which is oriented in the direction of the locking surface of the locking slide. The guide ramp ensures that, after the cam has been pressed into the recess by a force acting on the lid, the cam can again reach the lid locking position from the locking position when the lid locking element is rotated in the opposite direction, in such a way that the cam slides along the guide ramp. The guide ramp is oriented, for example, approximately parallel to the starting ramp, but is preferably constructed somewhat shorter. The guide ramp opens, for example, at one end into the first locking surface and at the second end into the locking surface of the locking slide.

[0037] According to another design, the preparation container has at least one inner tank and at least one housing. The housing surrounds the inner tank in the circumferential direction, preferably over the entire circumference. The inner tank can be removed from the housing and can be placed into the housing, preferably can be releasably locked with the housing. It is preferably provided that the lid locking element is at least partially supported on the underside of the rim of the inner tank at least in the lid locking position in order to transmit forces in the axial direction onto the housing. Preferably, the inner tank has an upper rim, which extends at least partially outward in the radial direction. Preferably, the lid locking element is supported on the housing of the preparation container and is at least partially, in particular completely, supported on the housing in the axial direction and in the radial direction.

[0038] In order to advantageously define an end position, for example a lid locking position, according to another design it is provided that the lid locking unit has at least one stop element. The stop element limits the movement of the lid locking unit in the lid locking position. Preferably, the stop element is configured as a protrusion on the lid locking element, in particular on the locking slide. If there are a plurality of locking slides, it is not only provided that the stop element is configured on at least or exactly one of the plurality of locking slides or on at least or exactly two of the locking slides, or that a stop element is configured on each of the locking slides. The stop element, for example, cooperates with the cams in such a way that the cams rest against the stop element in the lid locking position. For example, the stop element protrudes from the locking surface of the locking slide. Preferably, exactly one cam cooperates with exactly one stop element in order to define the lid locking position. Preferably, this cam is the cam which is arranged further away from the support unit in the circumferential direction compared to the other cams. This position ensures that one cam is reliably identified as resting against the stop element.

[0039] Furthermore, according to a further design variant, in particular, the lid locking unit has at least one lid locking element which is supported in a rotatable manner, and furthermore at least one engagement element and at least one transmission element. Advantageously, the engagement element is configured for a joint action with the kitchen device base, for example by the engagement element being able to be moved by the kitchen device base when the preparation container is arranged in the accommodation region. The engagement element and the lid locking element are connected to one another via the transmission element in such a way that a rotation of the engagement element about a rotation axis, which for example coincides with the longitudinal axis of the preparation container, causes a rotation of the lid locking element. For example, the engagement element, the lid locking element and the transmission element rotate about a common rotation axis.

[0040] In particular, the transmission element and the engagement element are configured in one piece. The transmission element is then connected to the lid locking element in a form-fitting manner in order to enable a joint rotation. Alternatively, the lid locking element, the transmission element and the engagement element are configured in one piece. For example, the lid locking element, the transmission element and the engagement element are configured from plastic. Preferably, the lid locking element, the transmission element and the engagement element are supported in a rotatable manner in the housing of the preparation container. For example, the inner pot can be removed from the housing, wherein the lid locking element, the transmission element and the engagement element remain in the housing. Preferably, the lid locking element and / or the transmission element and / or the engagement element are configured in such a way that they at least partially surround the inner pot as long as this is placed in.

[0041] Preferably, according to a further design variant of the preparation module, the inner pot has at least one rib, in particular at the foot region. The rib projects, for example, in the radial direction from the foot region. The rib is preferably oriented orthogonally to a rotation axis of a tool for the inner pot, or the rib is preferably in a plane from which the rotation axis is the face normal. Preferably, the housing, in particular the locking unit in the housing, has at least one engagement rib. In the locked position of the locking unit, the engagement rib is arranged in such a way that it collides with the rib on the inner pot when the inner pot is to be placed in the housing. Thereby, it is prevented that the inner pot can be placed in the housing when the housing is arranged on the kitchen device base, i.e. in particular only afterwards. When the housing is arranged alone on the kitchen device base, a joint action with the actuating unit prevents the unlocking of the locking unit from occurring. In the unlocked position of the locking unit, the inner pot can be placed in the housing.

[0042] Furthermore, the application relates to a kitchen device having at least one kitchen device base and at least one preparation module according to one of the embodiments, which has at least one preparation container and in particular at least one lid. Preferably, the kitchen device base is constructed and arranged in such a way that the preparation module, in particular the preparation container, and the kitchen device base interact at least partially form-fittingly in a receiving area. It is also provided in particular that the preparation module, in particular the preparation container, is placed only in the receiving area.

[0043] Preferably, the receiving area has at least one actuating unit for interacting with a cooperating element of the preparation module, in particular the preparation container. Preferably, the movement of the actuating unit can be transmitted to the cooperating element, so that the cooperating element can be moved by the actuating unit. For example, the preparation module, in particular the preparation container, can be mechanically locked in the receiving area by means of the actuating unit and the cooperating element.

[0044] The actuating unit has at least one drive unit and at least one actuating element held in a rotationally movable manner about a rotation axis and at least one stationary holding element. The kitchen device base has at least one control unit which is arranged and constructed for recognizing whether the movement of the cooperating element is blocked and stopping the movement of the actuating element when a blockage is recognized.

[0045] According to a variant of the application, a blockage is present, for example when the locking mechanism is in the locked position. Advantageously, the control unit is arranged and constructed for recognizing that the locking mechanism is in the locked position and stopping the movement of the lid locking unit, in particular by stopping the drive unit when the locking mechanism is in the locked position.

[0046] Preferably, the control unit is arranged and constructed for recognizing the locked position using at least one current intensity of the drive unit, in particular in such a way that the current intensity increases when the lid locking unit is in the locked position. Alternatively or additionally, recognition takes place using at least one sensor, for example a sensor which detects the position and / or a change in position of the lid. If the sensor recognizes a translational movement of the lid, the movement of the actuating unit is stopped, for example by switching off the drive unit. For example, it can be detected by means of the sensor whether the locking element is resting against the first and / or second locking surface.

[0047] For example, a handling element held in a rotatable manner cooperates with a mating element of the preparation container and drives the mating element in order to lock or unlock the lid together with the lid locking unit, and / or in order to lock the preparation container with the kitchen device base, and / or in order to initiate a mechanical function on the preparation module. Preferably, the rotational speed of the handling unit, in particular of the handling element, of the kitchen device base and the rotational speed of the mating element of the preparation module are identical when rotating.

[0048] Preferably, the rotation of the mating element causes the locking of the preparation container with the kitchen device base. In particular, the mating element of the preparation module has at least one action section projecting in the direction of the axis of rotation and at least one entrainment mating element. The entrainment mating element has at least one entrainment mating surface for cooperating with an entrainment element of the kitchen device base. The entrainment mating surface is arranged offset with respect to the action section in a direction parallel to the axis of rotation of the mating element. In this way, an advantageous cooperation of the action section with the holding element of the kitchen device base can be achieved in order to lock the preparation container.

[0049] The mating element has at least one recess into which the entrainment element can be inserted, in particular in a direction parallel to the axis of rotation, when the preparation module is placed into the receiving area. For example, by rotating the mating element, the at least one action section is rotated under the at least one holding element, thereby locking the preparation container with the kitchen device base. The recesses are preferably arranged adjacent to the entrainment mating element. The number of recesses preferably corresponds to the number of entrainment elements of the kitchen device base. Likewise, the number of action sections corresponds to the number of holding elements of the kitchen device base in order to enable an advantageous cooperation of the kitchen device base with the preparation module.

[0050] The kitchen device base advantageously has a weighing function, so that food arranged in or on the preparation module can be weighed. In particular, a load cell is arranged on a foot of the kitchen device base and / or a load cell is arranged within the receiving area.

[0051] According to one design variant of the kitchen device, the control unit is designed and configured to, when the control unit recognizes that the locking mechanism is no longer in the locked position, in particular is completely outside the locked position, prompt the drive unit to move the lid locking unit into the lid release position. Alternatively or additionally, the control unit is designed and configured to, when a predetermined waiting time has elapsed after the control unit recognizes that the locking mechanism is in the locked position, prompt the drive unit to move the lid locking unit into the lid release position. For example, in the waiting time, a rotating liquid whirl can subside, so that no more forces from the preparation chamber act on the lid and the lid can be opened.

[0052] A further design option of the kitchen device provides that the control unit is designed and configured to, after the locking mechanism has been identified in the locked position, cause the drive unit to move the lid locking unit again into the lid locking position and, in particular after a predetermined waiting time, to move the lid locking unit again in the direction of the release position. If the lid locking device is blocked by the locking mechanism in the locked position when moving in the direction of the lid release position, the locking element, for example the lug, is preferably moved again into the locked position, i.e. again into the initial position, here the lid locking position. During the waiting time, for example forces from the preparation chamber can decrease, after which the opening attempt is resumed by moving the lid locking unit in the direction of the release position. In particular, the lid locking element is rotated in the direction of the release position.

[0053] It is particularly preferred that the control unit is designed and configured to repeat the above-described procedure individually or in combination until the lid locking unit is moved into the release position and the locking mechanism does not reach the locked position.

[0054] Furthermore, the invention relates to a method for operating a preparation module having a preparation container and a lid or a functional module, in particular a preparation module having at least some of the features of the above-described embodiments. The method has at least the following method steps:

[0055] - rotating a lid locking unit on the preparation container about an axis of rotation at least between a lid release position and a lid locking position in order to lock and unlock the lid. Preferably, the rotation of the lid locking unit is caused by means of a manipulation unit of the kitchen device base.

[0056] - bringing a locking mechanism into a locked position during the rotation of the lid locking unit in the direction of the lid release position when at least one force from the preparation chamber acts onto the lid, wherein said bringing the locking mechanism into the locked position comprises a translational movement of the lid relative to the preparation container, in particular in a direction parallel to the axis of rotation. Said "bringing" is caused by the force acting onto the lid, alternatively this force can also be exerted by the user when pulling the lid during unlocking, for example.

[0057] Further design options of the functional and structural features of the method result from the description of the embodiments of the preparation container, the kitchen device base or the kitchen device and its functions.

[0058] Furthermore, the invention relates to the use of a preparation module, in particular according to one of the described embodiments, on a kitchen device base, in particular on a kitchen device base according to one of the described embodiments or on a kitchen device according to one of the described embodiments.

[0084] In the different figures of the drawing, identical parts are always provided with the same reference signs.

[0085] For the following description, the invention is not restricted to the embodiments and is not limited here to all or to the combination of the features described, but rather, each individual feature of the described / each embodiment, in isolation and in combination with any feature of the other embodiments, is also of significance for the subject matter of the invention.

[0086] Figure 1 An embodiment of a preparation module 1 is shown, which is provided for arrangement in a receiving region 2 of a kitchen device base 3 of a kitchen device 4. The preparation module 1 here comprises a preparation container 1a and a cover 6. The preparation container 1 can be placed onto the flat upper side 3a of the kitchen device base 3 in order to interact with the kitchen device base 3. The kitchen device base 3 has at least one combined display and input device 3b in the form of a touch screen in order to control the functions of the kitchen device 4. In addition, there can be further electromechanical input devices in the form of rotary switches.

[0087] The structure of the preparation container 1a can be derived in particular from Figures 4 to 12c andFigure 20 As can be seen from the image, the preparation container 1a has at least one preparation chamber 5 for containing food, for example, see [reference needed]. Figure 4 The preparation chamber 5 can be sealed with a lid 6, wherein the lid 6 can be locked to the preparation container 1a by a lid locking unit 7, as detailed below. Figures 2a to 2c As described. The cover 6 has a handle 45. The handle 45 has a first handle element 45a and a second handle element 45b, which are arranged in a generally V-shape relative to each other.

[0088] according to Figure 4 , Figure 5 and Figure 9 The preparation container 1a has an inner tank 10, within which a preparation chamber 5 is formed. The inner tank 10 of the preparation container 1a can be inserted into and can be releasably locked within the housing 11. The housing 11 is in Figure 5 , Figure 6 , Figure 7 and Figure 20 It is shown separately in the text. Figure 4 A fully assembled preparation container 1a with a locked inner canister 10 is shown. Figure 5 An exploded view is shown, i.e., a view of the inner tank 10 when inserted into or removed from the housing 11, for example for cleaning purposes. The electrical interface 9 of the preparation container 1a is fixedly connected to the inner tank 10. Furthermore, leads and electronic device channels 60, including the identification mechanism 55 described below, are arranged on the inner tank 10. A tool 26a (here, a tool for cutting and stirring) is fixedly connected to a removable tool holder 26. Alternatively, the tool 26a can be released from the tool holder 26. Thus, the tool holder 26 can be inserted into, and preferably locked into, the inner tank 10, with and without the tool 26a.

[0089] Advantageously, within the housing 11 of the preparation container 1a, a locking unit 27 of the lid locking unit 7, along with a mating element 12, a transmission element 13, and a lid locking element 8, are held in a manner capable of rotating about the rotation axis R or longitudinal axis L of the preparation container 1a. In the assembled state, for example according to Figure 4 The transmission element 13 is particularly arranged in the intermediate space between the inner tank 10 and the housing 11 and is rotatable. The mating element 12, the transmission element 13, and the lid locking element 8 are configured such that they surround the inner tank 10 (see especially...). Figure 9 ,exist Figure 9 The shell 11 has been hidden. Figure 6 A perspective view of the casing 11 without the inner tank 10 is shown. Figure 6 The preparation container 1a is shown in the partial assembly diagram. The inner tank 10 is removed. The locking unit 27 can rotate between stop positions on the tab 41 on the inner side of the housing 11.

[0090] The interaction between the tabs 41 and the guides 66 of the locking unit 27, for example, is advantageously implemented according to the tongue-and-groove principle. The locking unit 27 furthermore has grooves 65 in which the tabs 41 can be guided (see also Figure 8 ). In the state shown in Figure 6 , the carrier 28 of the locking unit 27 rests against the transmission element 13, so that the locking unit 27 or the carrier 28 cannot be rotated anticlockwise according to Figure 6 . Furthermore, the transmission element 13 cannot be turned as long as the locking unit has not been moved. The transmission element 13 is supported in the anticlockwise rotational direction on an end stop 46 on one of the tabs 41. From the position shown in Figure 6 , movement of the transmission element 13 in the clockwise rotational direction is limited by the other end stop 46 on the tab 41 (see Figure 7 ). Thus, two end stops 46 for the transmission element 13 are configured on the inside of the housing 11.

[0091] Figure 7 A perspective view into the housing 11 without any attachments, in particular thus only the sleeve, is shown. In this embodiment, the housing 11 is composed of a thermally insulating material, which here is plastic. Additional thermal insulation is ensured by the spacing between the inner pot 10 and the housing 11. In the inserted state, the inner pot 10 is surrounded by the housing 11 both in the entire circumferential direction and in terms of its height (see Figure 4 ). According to Figure 5 , 6 , 7 and 20, the housing 11 has the aforementioned tabs 41 on its inside, which serve to support the locking unit 27. Via the tabs 41, in particular axial forces parallel to the rotational axis R direction can be transmitted from the locking unit 27 to the housing 11. The housing 11 has a rim 43 projecting inwards in its lower region, on the inner end side 43a of which the fitted fitting element 12 is supported in the radial direction with the support point 58 (see in particular Figure 11 and Figures 12a to 12c ).

[0092] Below the tabs 41 shown on the right in Figure 7 , a channel is configured in which a first reset element 49 in the form of a spring here can be arranged according to Figure 20 . The first reset element 49 interacts in the fitted state with a protrusion 69 on the locking unit 27 (see for example Figure 8 ) in order to always urge the locking unit 27 towards the release position according to Figure 12c , by means of which the tool holder 26 can be inserted. Furthermore, a support element 64 for a second reset mechanism 50 is configured on the lower rim 43 (see in particular Figure 7 andFigure 7a ), which second reset mechanism is likewise in the form of a spring here. In Figure 7a , the second reset mechanism 50 is shown for the sake of understanding only. The reset mechanism 50 is held in a receiving portion 67 on the locking element 27 in the assembled state (see Figure 8 , Figure 9 , Figure 10a and Figure 10b ).

[0093] In order to install the inner tank 10 in the housing 11, the inner tank 10 is first placed into the housing 11, see Figure 5 . Subsequently, the tool holder 26, which is fitted with a tool 26a (here a cutting and stirring tool), is passed through the inner tank 10 and through the locking ring 29 of the carrier 28 of the locking unit 27. The locking ring 29 has an inner diameter of between 29.5 mm and 35.5 mm, in particular of approximately 32.5 mm, for example. The locking ring 29 is connected to the outer ring 30 of the carrier 28 by means of retaining tabs 31. Furthermore, the carrier 28 has a mating rib 75 on the inner side (see in particular Figure 8 ), which, as described below, is configured to cooperate with a rib 74 on the inner tank 10 (see Figure 5 ). Figure 12c An exemplary view of the preparation container 1a with the placed inner tank 10, but without the tool holder 26, is shown from below. The electrical interface 9 of the inner tank 10 is accessible from the underside of the preparation container 1a, so that it can cooperate with the electrical mating interface 32 when the preparation container 1a is arranged in the receiving area 2 of the kitchen device base 3 (see Figure 1 , Figure 16 and Figure 17 ).

[0094] In particular according to Figure 5 , the inner tank 10 has at least one rib 74, in particular on the foot region. The rib 74 is oriented orthogonally to the axis of rotation of the tool 26a for the inner tank 10. Preferably, the housing 11, in particular the locking unit 27, has at least one mating rib 75 (see Figure 6 and Figure 8 ). In the locked position of the locking unit 27, the mating rib 75 is arranged so as to collide with the rib 74 on the inner tank 10 when the inner tank 10 is attempted to be inserted into the housing 11. Thereby, the inner tank 10 is prevented from being able to be inserted into the housing 11 when the housing 11 (without the inner tank 10) is arranged on the kitchen device base 3, in particular so that the inner tank 10 cannot be inserted at a later time. The cooperation with the operating unit 2a prevents the locking unit 27 from being unlocked when the housing 11 is arranged alone on the kitchen device base 3. In the unlocked position of the locking unit 27, the inner tank 10 can be inserted into the housing 11.

[0095] In Figure 12c the locking unit 27 is in a first position, a release position, in which the tool holder 26 can be passed through the locking ring 29. The locking unit 27 has a handling grip 33 with which the locking unit can be rotated from the first position (release position) according to Figure 12c and Figure 12b into the second position (locking position) according to Figure 12a . As an alternative or in addition to the first handling grip 33, the locking unit 27 has an alternative handling grip 33a which can be reached from below the preparation vessel 1a.

[0096] According to Figure 12b the tool holder 26 is inserted, however not yet locked with the locking unit 27. The locking takes place by the handling grip 33 (or the alternative handling grip 33a) being placed by the user in the second position according to Figure 12a . According to Figure 8 and Figures 12a to 12c the locking ring 29, through which the tool holder 26 can be passed, has a plurality of hooks 38 on its inner circumference, which are configured for a form-fitting interaction with the locking ring 29. If the locking unit 27 is rotated and thus also the hooks 38 on the locking ring 29, a form-fitting locking of the tool holder 26 with the locking unit 27 is achieved by the hooks 38. Since the tool holder 26 also passes through the inner pot 10, the inner pot 10 is also locked with the housing 11 by the locking of the tool holder 26. For cleaning purposes, the tool holder 26 with the tool 26a and the inner pot 10 can be removed in the reverse order, in particular by unlocking by moving the handling grip 33 from the second position according to Figure 12a into the first position according to Figure 12b .

[0097] The locking unit 27 has a first reset mechanism 49 in the form of a return spring (see Figure 20 ). The first reset mechanism 49 acts between the housing 11 and the locking unit 27 in order to press the locking unit 27 at least when the tool holder 26 is not inserted in the direction of the release position of the tool holder 26 according to Figure 12c . As a result, the handling grip 33 is also always in the position according to Figure 12c . Furthermore, a second reset mechanism 50 is provided, in particular also in the form of a return spring, which acts between the locking unit 27 and the mating element 12. The second reset mechanism 50 presses the mating element 12 in the direction of the second position, which here corresponds to the locking position, so that when no tool holder 26 is present or a present tool holder 26 is not locked as shown in Figure 12a the preparation vessel 1a cannot be arranged in the accommodation area 2 of the kitchen device base 3.Figure 12b In the state shown, it is impossible to apply to the containing area 2.

[0098] The cover locking element 8, the transmission element 13, and the mating element 12 are based on Figure 6 , Figure 9 , Figure 10a and Figure 10b They are connected to each other in a torsion-resistant manner, so that they can be rotatably supported within the shell 11 of the container 1a about the axis of rotation R (see especially...). Figure 6 and Figure 9 The cover locking element 8 is supported on the inner surface of the housing 11 or sleeve at its upper edge 73, which has multiple radial support portions 62 (see...). Figure 6 , Figure 7 and Figure 10b The unit, consisting of the cover locking element 8, the transmission element 13 and the mating element 12, is supported in the housing 11, particularly via the support portion 62 of the cover locking element 8 and the support portion 58 of the mating element 12.

[0099] In this embodiment, such as especially Figure 9 and Figure 10a , Figure 10b As shown, the mating element 12 and the transmission element 13 are constructed as a single piece, wherein the unit shape formed by the mating element 12 and the transmission element 13 is connected to the cover locking element 8. The transmission element 13 has three substantially vertically extending arms, the ends of which are respectively connected to the cover locking element 8.

[0100] In particular, according to Figure 5 , Figure 6 and Figure 9 In the assembled state, the mating element 12 can rotate between a first position and a second position. Since the lid locking element 8 and the mating element 12 are connected to each other in a torsion-resistant manner via the transmission element 13, when the mating element 12 is in the first position, the lid locking element 8 is in the lid-released position, and when the mating element 12 is in the second position, the lid locking element 8 is in the lid-locked position. Through this combined action, the rotation of the mating element 12, particularly caused by the kitchen equipment base 3, causes the lid 6 to... (see below) Figures 2a to 2c The automatic locking and unlocking are described. The mating element 12 is constructed to work in conjunction with the kitchen equipment base 3, and especially with the operating unit 2a in the housing area 2.

[0101] like Figure 1 As shown, the preparation module 1, here a preparation container 1a with a lid 6, can be placed into the receiving area 2 of the kitchen equipment base 3. In particular, the preparation container 1a can be arranged in the receiving area 2 with or without the lid 6 at its base area. Figure 16 ,Figure 17 and Figure 21 A detail view of the upper side 3a of the kitchen device base 3 with the accommodation area 2 is shown. The accommodation area 2 has a handling unit 2a with a drive unit 15, a handling element 16 rotatably held about a rotation axis R1 and three positionally fixed holding elements 17. The holding elements 17 are arranged at an angle of approximately 120° to one another and each have a convexly curved holding face 17a, which is oriented in the direction of the upper side 3a.

[0102] In order to be able to move the handling element 16, the drive unit 15, in particular according to Figure 21 has at least one motor 15a and at least one gearwheel 15b. Figure 21 An embodiment of the kitchen device base 3 is shown in a partial cut. The gearwheel 15b is in a form-fitting engagement with the handling element 16 in order to rotate the handling element 16. For example, the handling element 16 has a toothing, into which the gearwheel 15b engages, which is not shown. The motor 15a is directly connected to the gearwheel 15b, only the shaft end of the motor is shown.

[0103] The handling element 16 is rotatably arranged above the holding elements 17. The handling element 16 has three belt drive elements 18, which completely overlap in a first position, shown in Figure 16 , in a direction parallel to the rotation axis R1 of the handling element 16. Above the belt drive elements 18, respectively, a lead-in element 39 is arranged, which, like the holding elements 17, is positionally fixed. According to Figure 16 , in the first position, the lead-in elements 39 likewise completely overlap the belt drive elements 18 or the holding elements 17 in a direction parallel to the rotation axis R1. The electrical contacts of the mating interface 32, which is configured for a joint action with an electrical interface 9 of a preparation container, for example shown in Figure 11 , are covered with a contact cover 40. The handling unit 2a surrounds a centrally arranged tool interface 57, which is configured for a form-fitting joint action with the tool holder 26 (see Figure 11 ) and for a splicing with the tool holder, when the preparation container 1a is arranged in the accommodation area 2.

[0104] The holding element 17 and / or the entraining element 18 and / or the introduction element 39 has a width of approximately between 23 mm and 27 mm, for example, in the circumferential direction. In particular, the width is approximately 25 mm. The entraining element 18 has a height of between 3.5 mm and 5.5 mm, preferably, in the direction parallel to the axis of rotation R. In particular, the height is approximately 4.5 mm. The handling unit 2a has a height of approximately 16 mm to 20 mm, in particular, approximately 18 mm, from the upper side 3a of the kitchen device base 3 up to the upper side of the contact cover 40. The introduction element 39 has a height of approximately between 21 mm and 25 mm, preferably, from the upper side 3a of the kitchen device base 3. In particular, the height is approximately 23 mm. The handling unit 2a has a radius of approximately 45 mm to 55 mm, in particular, approximately 50 mm, from the axis of rotation R1. The same applies to the handling element 16 and the contact cover 40. The introduction element 39 and / or the entraining element and / or the holding element 17 has a radius of approximately 49 mm to 61 mm, preferably, from the axis of rotation R1. In particular, the radius is approximately 53.5 mm.

[0105] In order to initiate the mechanical function on the preparation container 1a, the handling element 16 with the entraining element 18 can be rotated by the drive unit 15 at least to a first position according to Figure 17 In the first position, the entraining element 18 is pivoted out of the overlap with the holding element 17 and the introduction element 39 in the direction parallel to the axis of rotation R1.

[0106] The handling unit 2a protrudes on the upper side 3a of the kitchen device base 3 so that the handling unit 2a can at least partially enter into the lower side of the preparation container 1a when the preparation container 1a is inserted into the accommodation area 2.

[0107] In the state in which the preparation container 1a is applied within the accommodation area 2 of the kitchen device base 3, for example, according to Figure 11 , Figure 16 , Figure 17 , Figure 18 and Figure 19 , the introduction element 39, the entraining element 18 and the holding element 17 each pass through the fitting element 12 via one of the recesses 63. The recesses 63 are dimensioned so that the passage can only be achieved when the introduction element 39, the entraining element 18 and the holding element 17 completely overlap in the direction parallel to the axis of rotation R1. The recesses have a width of approximately 24 mm to 28 mm, in particular, approximately 26 mm, in particular, in the circumferential direction. Furthermore, the handling unit 2a passes into the fitting element 12 from below through the central opening (see Figure 10b and Figure 19 ). The central opening has a radius of approximately 47 mm to 57 mm, in particular, approximately 52 mm.

[0108] The electrical mating interface 32 of the kitchen device base 3 comes into contact with the electrical interface 9 of the preparation container 1a, for example according to Figure 11 , when it is placed in the accommodation area 2. Furthermore, the tool interface 57 of the accommodation area 2 is also connected with the corresponding interface of the tool holder 26 (see in particular Figure 11 ).

[0109] The display and input device 3b is arranged on the device front of the kitchen device base 3, the device back being located opposite (see Figure 1 ). When the preparation container 1a is arranged in the accommodation area 2, the handle 61 of the preparation container 1a is oriented towards the display and input device 3b. Furthermore, the handling unit 2a is oriented such that the lead-in element 30 of the handling unit 2a is oriented approximately on one imaginary line with the handle 61. This lead-in element 39 is oriented in the direction of the device back. The handling unit 2a is essentially circularly configured. From the lead-in element 39, which is oriented on one line with the central axis of the handle or of the display and input device 3b, two further lead-in elements 39 are distributed uniformly in the circumferential direction. In the circumferential direction opposite the aforementioned lead-in element 39, the electrical mating interface 32 is arranged (see Figure 16 and Figure 17 ). The electrical mating interface 32 is oriented in the circumferential direction in the direction of the handle 61 or of the device front. This arrangement assists the positioning of the preparation module 1 when it is placed, for example, slightly tilted forwards or backwards. Either the rear lead-in element 39, which is arranged on the imaginary line on the side facing the back of the kitchen device base 3, guides, or the two front lead-in elements 39, which are arranged on the side of the electrical mating interface 32, guide, said front lead-in elements assisting the rough forward orientation of the contacts relative to the mating interface 32.

[0110] The rotation of the entraining element 18 relative to the holding element 17 and the lead-in element 39 between the first position according to Figure 16 and the second position according to Figure 17 is advantageously used to cause a rotation of the mating element 12, for example in order to cause a mechanical function within the preparation container 1a, in particular in order to lock the preparation container 1a with the kitchen device base 3. The rotation preferably takes place by an angle of approximately 30°, wherein preferably first an angle of approximately 32° is reached and then a reset of approximately 2° takes place in order to reduce the stress in the components moved.

[0111] When the handling element 16 is rotated, the entraining element 18 is rotated, which respectively cooperates with the entraining cooperation face 53 of the entraining cooperation element 52 of the mating element 12 (see Figure 10a , Figure 10b and Figure 19) and thereby also a rotation of the engagement element 12 in the intermediate space between the inner pot 10 and the housing 11. The engagement element 12 has a plurality of action segments 51 projecting in the direction of the rotation axis R1, which each have a driving engagement element 52 with a driving engagement face 53. The rotation axis R, R1 and the longitudinal axis L are preferably coaxial when the preparation vessel 1a is placed into the receiving area 2. The driving engagement face 53 is arranged offset to the action segments 51, i.e. above the action segments 51, in a direction parallel to the rotation axis R1. By the rotation of the engagement element 12, the action segments 51 of the engagement element 12 are rotated under the concavely curved holding element 17, thereby locking the preparation vessel 1a with the kitchen device base 3. In Figure 18 the locking state is shown in a sectional view.

[0112] Since the engagement element 12 is connected torsionally resistant about the rotation axis R with the transmission element 13 and the lid locking element 8, the lid 6 is simultaneously locked or unlocked with the preparation vessel 1a when the engagement element 12 is moved, by the locking slide 34 (as described below with regard to Figures 2a to 2c ) and the lugs 35 on the underside of the lid 6.

[0113] The advantageous locking of the preparation vessel 1a with the kitchen device base 3 is thus achieved in the shown embodiment simultaneously with the locking of the lid 6 with the preparation vessel 1a. The unlocking of the preparation vessel 1a from the kitchen device base 3 takes place in the reverse order, i.e. in such a way that the driving element 18 in the opposite direction interacts with the driving engagement elements 52, in particular with the reset face 54, of the engagement element 12 and the engagement element 12 is rotated in the opposite direction until the action segments 51 of the engagement element 12 no longer overlap the holding element 17 in the direction parallel to the rotation axis R, so that the holding element 17, the driving element 18 and the lead-in element 39 can again move outwards through the recess 63 when the preparation vessel 1a is lifted from the receiving area 2 (see in particular Figure 18 ).

[0114] At the same time, by the rotation of the engagement element 12 in the opposite direction, the lid locking element 8 is also rotated in the opposite direction, i.e. in the direction of the lid release position, via the transmission element 13, so that the lid 6 can be removed in the lid release position.

[0115] However, if there is a pressure in the preparation chamber 5 during the rotation in the direction of the lid release position or the user pulls the lid 6, the blocking mechanism 19 enters the blocking position (as described below with regard to Figures 2a to 2c ) and thus prevents a continued rotation of the lid locking element 8 and the engagement element 12. This blocking is recognized by the drive unit 15 or by the control unit from the increased current strength and the rotation is stopped.

[0116] Preferably, the setting is then first followed by a rotation in the opposite direction, i.e. the application section 51 is rotated again under the holding element 17 and the locking runner 34 is rotated again into the lid locking position. After a predetermined time or by a renewed triggering by the user, the renewed unlocking or lid release process is initiated.

[0117] Figures 2a to 2c An upper part of the preparation module 1 is shown, i.e. a lid 6 which is placed onto the preparation container 1a in different locking states. The lid 6 has a total height of between approximately 24 mm and 28 mm, for example, in a direction parallel to the longitudinal axis L. In particular, the total height is approximately 26 mm. On the upper edge of the preparation container 1a, a lid locking unit 7 is arranged which can interact with the lid 6. Figure 2a The lid locking unit 7 is shown in the lid release position, Figure 2b The lid locking unit 7 is shown in the lid locking position, and Figure 2c The lid locking unit 7 is shown in a position between the lid locking position and the lid release position, in which position the locking mechanism 19 of the lid locking unit 7 is in the locking position. Since the locking mechanism 19 is in the locking position, the lid locking unit 7 is prevented from moving in the direction of the Figure 2a lid release position.

[0118] The locking mechanism 19 is in the locking position in accordance with Figure 2c the lid 6 is acted upon by a force parallel to the longitudinal axis L of the preparation container 1a, away from the preparation container 1a. This force is caused by a force acting on the lid 6 from the preparation chamber 5, for example a rotating wave from the food or a pressure present in the preparation chamber 5, or by the user trying to lift the lid 6 off the preparation container 1a.

[0119] In accordance with Figure 2c When the locking mechanism 19 is in the shown locking position, the lid locking unit 7 is moved at least partially in the direction of the lid release position. The locking mechanism 19 reaches the locking position by a translational movement of the lid 6, in particular in a direction parallel to the longitudinal axis L of the preparation container 1a (see Figure 2c ). The locking mechanism 19 comprises a plurality of first locking surfaces 20, a plurality of second locking surfaces 23 and a plurality of locking elements 21. By the locking elements 21 resting on the respective first locking surfaces 20, the translational movement of the lid 6 parallel to the longitudinal axis L is limited. The locking elements 21 are embodied here as radially inwardly projecting lugs 35 on the lid 6 (see also Figure 13 ), which likewise serve to lock the lid 6.

[0120] The lugs 35 have, for example, a width of approximately 10 mm to 14 mm, in particular approximately 12 mm, and / or a depth in the radial direction of between 5 mm and 7 mm, in particular approximately 6 mm, and / or a height in the direction parallel to the axis of rotation R of between 3.5 mm and 5.5 mm, in particular approximately 4.5 mm.

[0121] The first and second locking faces 20, 23 are faces in the recess 22 in the locking channel 34, which is configured on the lid locking element 8 of the lid locking unit 7. The first locking face 20 has, for example, a width of between 5.5 mm and 7.5 mm, in particular approximately 6.5 mm. The locking channel 34 preferably has a height in the direction parallel to the axis of rotation R of approximately 6.6 mm to 8.6 mm, in particular approximately 7.6 mm. The lid locking element 8 is rotatably supported about the axis of rotation R, which coincides, for example, with the longitudinal axis L of the preparation container 1, at least between the lid release position and the lid locking position. The lid locking element 8 is essentially configured as a ring and can be rotated not only relative to the lid 6, but also relative to the preparation chamber 5 (see, in particular, the Figures Figure 2a and Figure 2b ). In order to enable the lugs 35 of the lid 6 according to Figures 2a to 2c to interact with the lid locking unit 7 or the lid locking element 8, the inner pot 10 according to Figure 4 and 5 has a number of recesses 59 in its upper edge 73 corresponding to the number of lugs 35. The recesses 59 are preferably arranged in pairs, wherein an angle of approximately 60° is formed between a pair of recesses 59, seen from the longitudinal axis L. An angle of approximately 120° is formed between two pairs of recesses 59, respectively. In the embodiment according to Figure 4 and Figure 5 , in which the inner pot 10 has an extension 42, the angle between the extension 42 and the first recess 59 adjacent to the extension 42 is, for example, approximately 60°. From any one adjacent recess 59 to the respective next recess 59, the angle is likewise approximately 60°.

[0122] The lid locking unit 7 has four locking runners 34 on the lid locking element 8, which cooperate in a form-fitting manner with lugs 35 in order to lock the lid 6 in such a way that it closes the preparation chamber 5. The locking runners 34 are rotatable in common with the lid locking element 8 about the longitudinal axis L or the rotational axis R relative to the lid 6 and relative to the preparation chamber 5. In order to cooperate with the lugs 35 constructed on the lid 6, the locking runners 34 each have a starting ramp 36, which, when the lid locking element 8 is rotated in the direction of the lid locking position, causes the lugs 35 to be moved axially in the direction parallel to the longitudinal axis L of the preparation vessel la in such a way that the lid 6 is pulled over the lugs 35 in the direction of the preparation chamber 5. The starting ramp 36 has a length of between 13 mm and 17 mm, in particular approximately 15 mm. When the lid locking element 8 continues to rotate, the lugs 35 each enter a recess 22 of the locking mechanism 19 and then slide out of the recess 22 over a guide ramp 47 until they finally each abut against a locking face 37 oriented essentially orthogonally to the longitudinal axis L in order to lock the lid 6. Preferably, the locking face 37 and the first locking face 20 are arranged offset from one another by approximately 2.5 mm to 4.5 mm, in particular approximately 3.5 mm, along the rotational axis R.

[0123] If the lid locking unit 7 is in the lid locking position according to Figure 2b If the lid locking unit 7 is in the lid locking position according to

[0124] According to the application, it is ensured by this function that the lid can only be opened by the user when the food can no longer overflow. It is furthermore ensured that the blocking of the opening of the lid 6 only takes place when a real force is acting on the lid 6. Unnecessary waiting times for the user are thereby avoided.

[0125] The rotatably supported lid locking element 8 is supported on the underside of the upper edge of the inner pot 10 at least in the lid locking position according to Figure 2c in order to achieve a force transmission in the direction parallel to the longitudinal axis L or the rotational axis R of the preparation vessel la.

[0126] One stop element 48 is constructed on the lid locking element 8 (see Figure 10b), in the lid locking position, the stop element abuts against exactly one of the lugs 35, 35b in order to prevent a continued rotation of the lid locking element 8 and thus to define the lid locking position. This abutment can be recognized, for example, by a control unit of the kitchen device base 3. The lugs 35, 35b are arranged at approximately 240° in a polar coordinate system oriented on the lid 6 (on the underside of the lid), in which the longitudinal axis L or the axis of rotation R forms the pole and the handle piece 45 is arranged at 0°. The lug 35, 35b against which the abutment can be recognized is thus one of the lugs 35 which is arranged farthest away from the support unit 14 compared to the other lugs. The recognition reliability of the abutment is thereby increased. The lid locking position is defined unambiguously by the use of only one stop element 48. It is preferably provided that a drive unit 15 of the kitchen device base 3, which preferably can rotate the lid locking element 8, detects an increased current strength on the motor and then switches off the motor. The stop element 48 is configured as part of the locking runner 34 and extends perpendicular to the locking face 37.

[0127] Figure 3a and Figure 3b An embodiment of the principle structure of the locking mechanism 19 is illustrated in a partially sectioned detail view, which illustrates the functional principle also for the locking mechanism 19 in Figures 2a to 2c . When the lid locking element 8 should be placed in the lid release position, a rotation of the lid locking element 8 according to Figure 3a in the direction of the arrow to the right is carried out starting from the lid locking position in Figure 13 in which the lug 35 arranged on the lid 6 (see, for example, Figure 3a ) abuts against the locking face 37. The lug 35 simultaneously forms the locking element 21 of the locking mechanism 19.

[0128] If now during the movement of the lid locking element 8 in the direction of the lid release position a force generated by the preparation chamber 5 acts onto the lid 6 or the lid 6 is pulled by the user, the locking element 21 or the lug 35 is moved by the translational movement of the lid 6 into the recess 22 of the locking mechanism 19 on the locking runner 34 until the lug 35 abuts against the first locking face 20 and the second locking face 23. The first locking face 20 limits the translational movement of the lid 6 away from the preparation vessel la and the second locking face 23, which is arranged obliquely, mechanically prevents a continued rotation of the lid locking element 8 in the direction of the lid release position (see the locking position according to Figure 3b ). This mechanical blocking is recognized, for example, by a control unit of the kitchen device base 3, which causes the lid locking element 8 to be rotated back into the lid locking position according to Figure 3a .

[0129] Figure 3c and Figure 3d An alternative embodiment of the principle structure of the locking mechanism 19 is illustrated in a partially sectioned detail view. According toFigure 3c The lid 6 is in a lid locking position in which the protrusion 35 of the lid abuts against the locking face 37. The protrusion 35 also forms here the locking element 21 of the locking mechanism 19. If the lid locking element 8 is now rotated according to Figure 3c to the right in the direction of the lid release position and a force is exerted onto the lid 6 from the preparation chamber 5 or the lid 6 is pulled by the user, the lid 6, and thus the protrusion 35, is moved in translation into the recess 22 until the protrusion 35 abuts against the first locking face 20. The translation movement of the lid 6 is detected for example by a not shown sensor and the continued movement of the lid locking element 8 towards the release position is stopped. In this embodiment, the recess 22 does not have a second locking face 23, the blocking being carried out by means of the control unit.

[0130] As described, the lid locking element 8 can be rotated according to Figures 2a to 2c between a lid release position and a lid locking position in order to lock the lid 6 with the preparation container la. In order to prevent the lid 6 from rotating around the rotation axis R of the lid locking element 8 during the movement of the lid locking element 8, the preparation module 1 according to Figures 2a to 2c , 4, 5, 13, 14 and 15 has a support unit 14 which is constructed in such a way that it allows an axial movement of the lid 6 in a direction parallel to the rotation axis R or longitudinal axis L, but at the same time prevents a rotation of the lid 6 when the lid is applied to the preparation container la. According to Figures 2a to 2c , Figure 4 , Figure 5 , Figure 13 and Figure 15 , the support unit 14 has a support element 24 in the form of an expansion 42 on the inner pot 10 and a support mating element 25 in the form of a recess on the lid 6.

[0131] The support mating element 25 and the support element 24 interact form-fittingly together in the applied state of the lid 6, so that the lid 6 cannot rotate around the rotation axis R, but can be removed from the preparation container la in a direction substantially parallel to the rotation axis R (see in particular Figure 15 ). The support element 24 in the form of the expansion 42 can be moved in the height direction of the support mating element 25 in the form of the recess, in particular during the locking of the lid 6 with the preparation container la. The different positions of the support element 24 in the support mating element 25 can be seen for example from Figures 2a to 2c . In the lid locking position according to Figure 2b , this position is different from the lid release position according to Figure 2a .

[0132] Additionally, the support element 24 and the support counter element 25 are configured such that the lid 6 can be tipped up about an axis defined by the support element 24 by pressure acting onto the handle piece 45. The support element 24 is configured as a substantially U-shaped extension 42 on the inner pot 10 in this embodiment. The extension 42 is configured in one piece with the inner pot 10. In particular according to Figure 4 and Figure 5 , the extension 42 is configured on an upper edge 73 of the inner pot 10. In order to simplify the introduction of the support element 24 into the support counter element 25, in particular, the support counter element 25 according to Figure 13 has two introduction bevels 44 configured opposite one another, which simplify the sliding-in of the extension 42 according to Figure 4 and Figure 5 when the lid 6 is applied to the preparation vessel 1a (see also Figure 15 ). According to Figure 13 and Figure 15 , the support counter element 25 is arranged in the region of the handle piece 45 of the lid 6.

[0133] Figure 13 The lid 6 for the preparation vessel 1 is shown from the underside. In the region of the handle piece 45, the lid 6 has a support counter element 25 in the form of an elongated recess, which extends substantially parallel to the axis of rotation R or parallel to the longitudinal axis L of the preparation vessel 1a when the lid 6 is located on the preparation vessel 1a. This support counter element 25 serves to prevent the lid 6 from rotating when the lid locking element 8 is moved, by form-fitting interaction with a support element 24 in the form of an extension 42 on the inner pot 10 (see Figures 2a to 3c , Figure 4 , Figure 5 and Figure 9 ) when the lid 6 is applied to the preparation vessel 1a. Four lugs 35 extend radially inwards. Each lug 35 has a beveled lug face 35a for interaction with a starting ramp 36 of the locking runner 34 (see Figures 2a to 2c ).

[0134] In a polar coordinate system oriented on the lid 6 (lid underside), in which the longitudinal axis L or the axis of rotation R forms the pole and the handle piece 45 is arranged at 0°, the lugs 35 are arranged approximately at 60°, 120°, 240° and 300°. Thus, on the circumference in both directions, the angle between the handle piece 45 and the respective first lug 35 is approximately 60°. The angle between two adjacent lugs 35 on one side of the handle piece 45 is also approximately 60°.

[0135] In order to ensure centering of the lid 6 on the preparation vessel 1a, the lid 6 has a plurality of centering elements 72 on the underside of the lid. According to Figure 13On the lid 6, exactly five centering elements 72 are configured. The centering elements 72 protrude in the region of the retraction 70 from the inner edge 71 of the retraction 70 in the direction of the longitudinal axis L. The centering elements 72 are arranged in particular with their free edges facing away from the inner edge 71. Each centering element 72 extends in the retraction 70 only over a part of the height of the inner edge 71.

[0136] The first centering element 72 is arranged on the circumference of the lid 6 opposite the handle piece 45. The second and third centering elements 72 are arranged on the circumference on the underside of the lid at an angle of approximately 90° and approximately 270° in a polar coordinate system in which the longitudinal axis L forms the pole and the handle piece is arranged at 0°. The second and third centering elements 72 are advantageously arranged opposite one another. Furthermore, the fourth and fifth centering elements 72 are arranged on one side of the support engagement elements 25 of the support unit 14, respectively.

[0137] At least the second and third centering elements 72 have a tab 72a which protrudes from the centering element 72 in the radial direction. The tab 72a is advantageously used for the axial positioning of the lid 6 in the state applied to the preparation container la.

[0138] Figure 14 An alternative embodiment of the support unit 14 is shown which is configured on the outside of the lid 6 and the preparation container la. Here, the support elements 24 are formed by the handle 61 of the lid 6, wherein the support engagement elements 25 are configured as tabs on the lid 6 which are configured on the right and left of the handle 61. It is also conceivable, however, that the support engagement elements 25 are arranged in the form of two tabs on the housing 11 and that the handle piece 45 is used as a support element 24.

[0139] Figure 15 A cross section is shown which passes through the handle 61 of the preparation container la and at least partially through the lid 6 in the region of the handle piece 45. In the shown cross section, the support engagement elements 25 are shown in the form of recesses which extend substantially parallel to the longitudinal axis L of the preparation container la, in which recesses the support elements 24 in the form of the extensions 42 protruding from the inner pot 10 are introduced. The extensions 42 are configured substantially U-shaped and are connected in one piece with the inner pot 10. The extensions 42 can be moved in the support engagement elements 25 in the vertical direction according to Figure 15 For the introduction during the application of the lid 6, the support engagement elements 25 have two oppositely arranged introduction bevels 44. Furthermore, the lid can be tipped over, for example by a pressure acting on the handle piece 45, about an axis defined by the support elements 24, so that the lid is opened at least on one side of the lid.

[0140] A first identification mechanism 56, constructed as a permanent magnet, is arranged in the area of ​​the protrusion of the handle 61. An identification mechanism 55, specifically arranged in the lead and electronic device channel 60, on the inner can 10 is configured to identify the presence and / or orientation (polarization) of the magnet. Thus, the control unit of the kitchen equipment base 3 can identify whether the inner can 10 is arranged within the housing 11.

[0141] Furthermore, a second identification mechanism 68, in the form of two permanent magnets, is provided in the cover 6, particularly in the handle 45. The identification mechanism 55 is configured to identify the presence and / or orientation of the permanent magnets. Up to four different covers 6 can be identified by different orientations (polarizations) of the permanent magnets.

[0142] By using the different orientations of the two permanent magnets—north-south, south-north, north-north, and south-south—a total of four codes can be queried. These codes, for example, allow identification of different embodiments of the cover 6 using the identification mechanism 55. Depending on the embodiment of the cover 6, the second identification mechanism 68, which is in the form of a permanent magnet, is preferably coded differently. Furthermore, the presence of the second identification mechanism 68 allows identification of whether or not the cover 6 is applied to the preparation container 1a.

[0143] Figure 22 An embodiment of functional module 6a is shown in a sectional view. Since functional module 6a has a cap interface, which here has, for example, a protrusion 35 on the inner edge 71 for cooperating with the cap locking unit 7 or cap locking element 8, this relates to a cap 6 constructed as functional module 6a. Functional module 6a has an accessory tool 76 that can be mechanically coupled to the tool 26a and / or tool holder 26 of the preparation container 1a via a connection interface 77 (see, for example, see...). Figure 5 This is particularly useful for transmitting torque to the accessory tool 76. Therefore, the accessory tool 76 can rotate about a rotation axis R1, which here coincides with the longitudinal axis L and the rotation axis R. The internal space 78 of the functional module 6a can be closed by means of a cover element 79, which can be removed from the functional module 6a and / or pivotally supported. In the assembled state, the functional module 6a partially protrudes into the preparation chamber 5 of the preparation container 1a or the inner tank 10.

It is expressly emphasized that the embodiments are not limited to the combination of all features, but rather that each individual sub-feature can also have inventive significance separately from all other sub-features.
